Letters Patent No. 101,270, dated March 29. 1870.

IMPROVEMENT IN 'WOD PAVEMBNTS.

The Schedule referredto in these Letters Patent and making part n! the llame.v

To whom it may concern Be it known that I, S. H. INGERSOLL, otNew York city, in thel county of New York and State of New York, have, as'I believe, invented new anduseful Improvements in Street-Pavements; and I do hereby declare the following to be a full and exact description ofthe same, reference being had to the drawings that accompany and form a part of these specications.

l `igure1represents one manner of slotting or grooving wooden blocks for pavement, for the purposes hereinafter described.

This grooving consists in cutting out from each end of the block, forming a channel ot' more or less width, as may in this respect appear advisable, having a curved base line, as indicated by dotted lines nin the side view of single block in this said tig. 1.

The'ohject of my invention is to construct a roadway of wooden blocks, set with the grain ofthe wood running vertically, so prepared and arranged as to provide for the expansion and contraction of the wood, so that puffing up, occasioned by the former, and the loose rickety condition resulting from the latter, may both be avoided, and also to secure good footing for the horses.

My invention consists in the peculiar disposition and arrangement of grooves or channels and rebates in the blocks that form the pavement or roadway, for which please see drawings.

Letter A represents blocks of wood, which may be six or seven inches in height, three to four inches in thickness, and in width six to twelve inches, according as the dimensions of the plank from which they are taken will provide.

B, grooves or channels cut in the blocks A, as illustrated in fig. l of the drawings. These in width may be one inch or so, extending both horizontally and vertically toa degree that experiment shall demonstrate to secure the best results of t-he device.

The substructure for these blocks A may be planking or gravel, broken stone, concrete, or cement.

The spaces B are to he filled in the usual'way with tar and gravel or broken stone, or any suitable material that will keep well in place and presenta firm and rough or not slippery surface to the foot of the-horsc. The manner of placing and arranging the blocks with 'relation to each other can be well understood from the drawings.v

lVhat I claim as my invention, and desire to secure by Let-ters Patent, is-

The blocks A A A, when provided with the channels B, when said channels are of the form illustrated and the blocks arranged as described and specified.

In testimony whereof I have signed my name to this specification in the presence 'of two subscribing wit- S. H. INGERSOLL.
